Check rail device

ABSTRACT

A check rail arrangement for a switch or an intersection, the arrangement including a grooved rail ( 16 ) provided with a grooved rail head ( 14 ), a groove ( 18 ) and a lip ( 52 ), and a check rail ( 12 ) which is supported at least on the lip and is arranged by a fixing means in such a way that it can be displaced in relation to the grooved rail. The aim of the invention is to be able to easily displace the check rail. To this end, a fish-plate block ( 40 ) extends from the grooved rail ( 16 ), the fish-plate block including a longitudinal groove ( 42 ) which extends perpendicularly to the longitudinal direction of the grooved rail and in which a slot pin ( 44 ) engages in an adjustable manner. The slot pin can be tightened by means of a screw ( 46 ) extending from the check rail ( 12 ).

The invention relates to a check rail arrangement for a switch orintersection, comprising a grooved rail with a grooved rail head, agroove and a lip, a strip or secondary rail extending along the groovedrail, a check rail supported on at least the lip or machined lip andarranged so as to be adjustable relative to the grooved rail, a supportelement extending from the grooved rail and having an elongatereceptacle extending transversely of the longitudinal direction of thegrooved rail, in which elongate receptacle a fastening element isadjustably arranged, from which extends a first fastening meansconnected with or supported on the check rail

The purpose of check rails is to guide wheels in the area of switches orintersections where there is a gap. A corresponding arrangement is knownfrom EP 0 830 480. A check rail box extends along the arrangement,fastening means such as bolts, by means of which the check rail can befixed, are accessible to enable a readjustment or replacement. As aresult, the switch or intersection requires a large-scale construction,so cost-related disadvantages arise.

In a check rail arrangement according to DE 93 02 349 E1, a check railis supported both laterally on the grooved rail foot and on the lip.

A check rail arrangement of the initially mentioned type is known fromDE 297 19 799 U1. In this case, a check rail can be adjusted relative toa grooved rail by means of a support element in the form of a supportplate extending from the grooved rail, which support plate can be weldedto a profiled strip which has a slot, into which a nut for a bolt can beinserted, extending transversely of the longitudinal axis of the groovedrail, by means of which bolt a check rail profile supported on the lipof the grooved rail can be tightened.

A readjustable guide device is described in DE 296 09 572 U1. In thiscase, a check rail is adjusted and fixed by means of a bolt connectionwhich can be fixed in a groove formed between transverse webs.

The object of the present invention is to form a check rail arrangementwith structurally simple measures which should enable a problem-freeadjustment of the check rail without the need for a check rail box.According to one aspect of the invention, it should also be ensured thatthere is a flush transition between the check rail and the lip of thegrooved rail in the end areas of the check rail arrangement.

According to the invention, the object is essentially solved in that twomutually adjustable elements are associated with the check rail at theunderside, the extent of which is variable transversely of thelongitudinal direction of the grooved rail to the desired extent, theone first element being supportable against the check rail strip and theother second element against the secondary rail or an element associatedwith it. In particular, the invention is characterized in that the checkrail is connected at the underside with a holder which is open at thesecondary rail side and that the first element of the mutuallyadjustable two elements is supported along a boundary of the holderextending in the longitudinal direction of the grooved rail and thesecond element is supported at the secondary rail or the elementassociated with it.

According to the invention and contrary to the known prior art, thecheck rail is fixed by means of fastening elements (locking devices)which are adjustable in elongate receptacles, which may be designated asslide slots, extending transversely of the longitudinal axis of thegrooved rail, which fastening elements are similar to slide or slotblocks, whereby a desired adjustment of the check rail to form a desiredgap or slot between grooved rail head and leading edge of the check railoccurs by means of adjustment mechanisms which are formed by mutuallyadjustable, in particular, wedge-shaped elements, of which one of theelements is supported on the check rail or on the holder extendingtherefrom and the other on the secondary rail or an element associatedwith it (adjustment devices). Consequently, a precise width setting ismade possible without the need for plates which are used according tothe prior art to align the check rail.

Fastening elements such as bolts, both for the locking devices and forthe adjustment devices, are accessible from the top of the check railwithout the need for a check rail box or an opening of an embedding.Moreover, the check rail strip can be loosened, readjusted and fastenedor exchanged with conventional tools.

The holder, functionally open at the secondary rail side, may bedescribed as an open cage which accommodates the first and secondelements, which are supported on one another in a wedge-like manner andadjustable to one another in such a way that the overall size of theelements can be changed transversely of the longitudinal direction ofthe grooved rail to the desired amount, one of the elements, as alreadymentioned, being supported directly or indirectly at the secondary railand the other element at the boundary or wall of the cage extending inlongitudinal direction of the grooved rail.

When adjustment of the first and second elements relative to oneanother, they are supported on surfaces extending a wedge-like manner.Furthermore, the first element, facing away from the check rail, isconnected with the second fastening means, such as the lock bolt, sothat when it is tightened the first element is adjusted in direction ofthe check rail, with the result that the second element supported on thesurfaces of the first element extending in a wedge-like manner yieldslaterally and thus pushes away the holder fixedly connected to the checkrail, i.e. the cage from the secondary rail, with the result that thegroove between the leading edge of the check rail and rail head narrows.

In particular, the holder is U-shaped, the first element being supportedon its transverse portion so as to be vertically adjustable. The uppersecond element, extending on the secondary rail, extends in turn throughthe holder between its side arms so as to be supported on the secondaryrail.

Preferably, the first element has a quadrangular geometry with aT-shaped surface in plan view, a first rectangular surface extendingalong the transverse portion of the holder and triangular surfacesextending along the lateral sides of the holder, a second rectangularsurface of a smaller width extending parallel to the first rectangularsurface and a T-shaped undersurface, the respective triangular surfacebeing the outer boundary of a respective first wedge-shaped section ofthe first element, on whose free outer surfaces, extending at aninclination to the surface of the first element, a second wedge-shapedsection of the second element is supported.

Furthermore, the first wedge-shaped sections of the first elementdelimit a central quadrangular section which has a bore with an internalthread for interaction with the second fastening element, i.e. theadjustment bolt.

The second element has a U-geometry with sloping or wedge-shaped sidearms which are supported on the first wedge-shaped sections of the firstelement.

It is possible, with structurally simple measures, to adjust the checkrail strip towards and away from the grooved rail head by means of thiswedge mechanism in order to set the width of the groove between theleading edge and grooved rail head.

To ensure a flush transition between the leading edge of the check railand the lip of the grooved rail or a corresponding structural profile inthe end region, a further embodiment of the invention provides that, asviewed in the longitudinal direction of the grooved rail, at therespective end of the check rail, a guide plate extending between thesecondary rail and the lip and supported thereon is associated with thecheck rail, the width of the guide strip being such that the leadingedge of the check rail merges smoothly with the inner surface of the lipof the grooved rail. The guide plate and the check rail are therebypenetrated by a common fastening means, such as a bolt, which is securedby a lock nut. As a result, there can be no relative movement betweenguide plate and check rail transversely of the longitudinal direction ofthe grooved rail, so that, by the fixing via the guide plate, the checkrail can be adjusted relative to the lip of the grooved rail such thatits leading edge merges with the inner surface of the lip in a flushmanner. The first element of the wedge mechanism, which is used toadjust the check rail, can also be used as a lock nut.

The check rail can be supported both on the machined lip of the groovedrail or another structural profile and the secondary rail or strip. Lipand secondary rail are thus supports for the check rail which has, inparticular, a strip geometry whose narrow sides extend at the grooved orsecondary rail side. Thus, a narrow side forms a leading edge of thecheck rail.

In particular, the check rail comprises a wear-resistant flat materialin which bores are integrated which are penetrated by first or secondfastening means such as bolts in order, on the one hand, to fix thecheck rail (lock bolts) and, on the other hand, to adjust the check railto the desired extent in the direction of the grooved rail head toobtain a desired groove width (adjustment bolt).

According to the invention, a separation between adjustment of the checkrail and fixing of the check rail more or less occurs. In particular,the adjustment takes place by means of a wedging mechanism, whereas thefixing takes place by means of slide blocks which are preferablydisplaceable in slide slots. In this case, the fastening means, such asbolts, which interact with the slide blocks or the wedge mechanisms,extend from the upper side of the check rail and are thus easilyaccessible. It is thereby not necessary for the bolts to pass throughelongate holes, whereby otherwise the danger of dirt deposits wouldexist to such a degree that a simple loosening of the bolt is no longerpossible.

The elongate receptacle in the support element, which may in particularbe a filler piece, extending between the grooved rail and the secondaryrail is, as mentioned, formed particularly as a groove to receive aT-shaped slide block, which is the fastening element for the check rail.Other geometries for adjusting the fastening element along the elongatereceptacle or groove, without an uncontrolled slipping out beingpossible, are also feasible. Thus, a dove-tailed geometry can also beselected.

The first fastening means, as lock bolts, pass through the check railand are screwed into the fastening element or slide block in order tothereby fix the check rail by tightening of the fastening means. Thehead of the fastening means thereby extends in a recess of the checkrail and is supported against it. The recess, which extends from theouter surface of the check rail is, in particular, a hole having acircular geometry, such that the space between the head of the bolt andboundary of the recess is determined by the size of a tool which is togrip the bolt head, so that only a limited accumulation of dirt ispossible.

To reduce the moment of resistance of the check rail strip duringbending, that is when the groove width is to be reduced, according toour own inventive proposal, slots extend from the longitudinal edge ofthe check rail at the side facing away from the grooved rail, i.e. onthe secondary rail side, extend transversely of the longitudinaldirection of the rail. The slots can then be covered by plates which arefixed by means of the first or second fastening means.

Depending on the length of the check rail arrangement, a plurality oflocking and adjustment units are accordingly provided for fixing andadjustment the check rail strip. 321 Accordingly, several filler piecesare present which have a through opening at the underside. This makes itpossible for any accumulated water to be able to flow along anunderlying plate, from which the grooved rail and the secondary railextend, to an opening of a drainage box.

Furthermore, the check rail arrangement is covered at the ends byclosure plates. Thus, an outwardly closed system is available, so thatcontaminations in the area between secondary rail and grooved rail belowthe check rail can be avoided.

With respect to the secondary rail, also referred to as a strip, itshould be noted that it can consist of flat material extending along thegrooved rail, which can be connected, e.g. welded, at the bottom to aplate forming a rail foot. This foot extends at the side facing awayfrom the grooved rail. Both the grooved rail and the secondary rail canbe arranged e.g. on concrete ties with an insulated Napla railfastening. Other known arrangements are also feasible.

The filler piece and the bolt connection connecting the grooved rail orits web and the secondary rail can be a high-tensile bolt which issecured e.g. with Nordlock plates. Preferably, high-tensile M27 boltsare suitable. The lock bolt should also be secured by means of Nordlockwashers.

The adjustment bolts, in turn, should be positively secured by washerswhich are bent on one or more flat faces of the bolt heads.

Further details, advantages and features of the invention can be foundnot only in the claims, the features found therein—alone and/or incombination—but also in the following description of a preferredembodiment found in the drawings, in which:

A check rail arrangement 10 intended for a switch or intersection of agrooved rail track can be seen in the figures, wherein a strip-shapedcheck rail 12 can be adjusted, relative to a head 14 of a grooved rail16 or a structural profile with a groove, to form a slot 18 of thedesired width. The slot 18 should thereby be narrower in the middleregion L3 than in the respective end regions (L2, L4) of the check railarrangement 10.

To securely fix the check rail 12, referred to hereinafter as a checkrail strip, while simultaneously enabling the desired adjustment, thecheck rail arrangement 10 comprises, on the one hand, locking units 20,22 and, on the other hand, adjustment units 24, 26. The same referencenumerals are basically used for the same elements in the description.

As can be seen in particular in the cross-sectional drawings, asecondary rail 28 or a similarly acting element extends along thegrooved rail 16, consisting of a flat material extending along thegrooved rail 16 as first section 30 and a welded plate 32 forming afoot, the plate 32 extending along the side of the base section 30facing away from the grooved rail. In this embodiment, secondary rail 28or its foot 32 and grooved rail 16 or its foot 34 are arranged onconcrete ties with insulated Nabla rail fastening which, in turn,extends from a base plate 36 that extends on the concrete tie.

Filler pieces 40, which are each connected or clamped together by meansof a bolt connection 42, are provided in the region of the locking units20, 22 extending between the grooved rail 16 or its web 38 and the basesection 30 of the secondary rail 20. In particular, the bolt connectionis a high-tensile bolt such as M27 bolts which are secured by means ofNordlock washers. However, in this respect, reference is made to knownconstructions.

At the check rail strip side and extending from the top surface, a slot42 extends in the filler piece 40 transversely of the longitudinaldirection of the grooved rail, in which slot there is slidably arrangeda fastening means in the form of a slide block 44, which is guidedsecurely in the slot 42 due to its geometry, e.g. a T-shaped ordove-tailed geometry. The slide block 44 has a boring with an internalthread to receive a first fastening means in the form of a bolt 46 (lockbolt), the head 48 of which extends in a recess, such as a boring 50,extending from the surface of the check rail strip 12. By shifting theslide block 40 along the slot 42, the check rail strip 12 can thereforebe adjusted toward the rail head 14 or away from it in order to therebyadjust the width of the groove 18.

As can be seen in the drawings, the check rail strip 12 is supported, onthe one hand, on the machined lip 52 of the grooved rail 16 and, on theother hand, by the secondary rail 28, which each form a support surfacefor the check rail strip 12. In this way, the check rail strip 12 isfixed in a form-locking manner on the respective support surface whenthe bolt 46 is tightened.

By means of the locking units 20, 22, it possible to adjust the checkrail strip 12 without the bolts 46 passing through elongate holes, whichwould become dirty and thus make handling more difficult.

As can be seen in the plan view of FIG. 1, several locking units 20, 22are provided depending on the length of the check rail arrangement 10,and likewise the adjustment units 24, 26, to be described in thefollowing, which make it possible to adjust the check rail strip 12 in acontrolled manner to the required degree. To facilitate this adjustment,i.e. to reduce the moment of resistance of the check rail strip 12against bending, slots 56, 58, 60, extending transversely of thelongitudinal axis of the check rail strip 12, extend from thelongitudinal edge 54 located at the secondary rail side. A correspondingslot 56 can be seen in FIG. 3. The slots can thereby be covered byrust-proof plates which are, in turn, secured by bolts 46 or secondfastening means in the form of adjustment bolts 58 extending from theadjustment units 24, 26. These will be described in greater detail withreference to FIGS. 5 and 7 to 12 and with reference to the adjustmentunit 26.

The adjustment unit 26 comprises a U-shaped cage 60 which extends fromthe underside of the check rail strip 12 and is, in particular, weldedto it. The cage 60 is open toward the secondary rail 28 or a similarlyacting element, the transverse portion 62 of the U-profile extendingparallel or essentially parallel to the secondary rail 28 and thus tothe grooved rail 16. Side arms 64, 66 extend at a right angle to thetransverse portion 62.

An insert, comprising a first element 70 and a second element 72, ismovable within the cage 60 in its axial direction, i.e. along itslongitudinal axis 68. The first and second elements 70 and 72 co-operatein the manner of a wedge mechanism, so that, depending on the relativepositions of the first and second elements 70, 72, the effective widthof the insert can be adjusted along transverse axis 74 of the cage 60and thus transversely of the grooved rail 16 or secondary rail 28.

Consequently, the check rail strip 12 can be shifted to the desiredextent in direction of the grooved rail 16 or its head 14 since thefirst element 70 is supported by its first outer surface 76 on thetransverse portion 62 of the cage 60 and the second element 72 by itsouter surface 78 on the secondary rail 28 or a corresponding elementextending along the grooved rail 14.

The first element 70 and the second element 72 thereby lie against oneanother at wedge—or ramp-shaped surfaces 80, 82 or 84 extending at aninclination to the longitudinal axis 68 and thus slide relative to oneanother, on axial displacement of the first element 70 towards thesecond element 72, in such a way that there is a change in the distancebetween the outer surfaces 76 and 78 of the first and second elements 70and 72, so that the desired bending of the check rail strip 12 is madepossible.

As can be seen in the drawings, the first element 70 consists of aquadrangular base section 86 which is penetrated by a boring 88 havingan internal thread. The wedge-shaped first sections 90, 92, forming thesupport surfaces 80, 82, extend laterally of the quadrangular section66. In a plan view, the first element 70 is T-shaped.

The second element 78 exhibits a U-geometry, its transverse portion 94at its outer surface (surface 78) abutting the secondary rail 28. Theside arms 96, 98 have a triangular geometry in longitudinal section, theundersides forming the surfaces 84 which are supported on the surfaces80, 82 of the first element 70.

The insert formed by the first and second elements 70, 72 can be axiallyadjusted relative to the cage 60 simply due to the fact that anadjustment bolt 58 passing through the check rail strip 12 engages inthe internal thread of the boring 88 of the first element 70. In thisway, the effective extent of the unit in the cage 60 can be adjusted asdesired, transversely of the longitudinal axis of the check rail unit,and the distance between the first and second elements 70, 72 or theirouter surfaces 76, 78 can thereby be modified.

The angle of inclination a of the surfaces 80, 82, on the one hand, and84, on the other hand, which are supported on one another, should be inthe range of 50°≦α≦70°, in particular a being about 60°.

To ensure that the check rail strip 12 at its leading edge mergessmoothly with the inner surface of the lip 52 at the respective endregion (line 101), a plate element 100 is provided, as shown in thecross-sectional view B-B (FIG. 4), which is supported, on the one hand,on the outer surface of the lip 52 of the grooved rail 16 and, on theother hand, at the secondary rail 28, i.e. on its surface facing thegrooved rail 16. The check rail strip 12 is connected with the plateelement 100 by a connecting means such as a bolt and a lock nut or asimilarly acting element such that a relative movement between them,transversely of the longitudinal direction of the grooved rail 16, isprevented. In this way, the check rail strip 12 can be located, relativethe grooved rail 16, by the position of the opening in the plate element100 through which the bolt extends, in such a way that the leading edgeof the check rail strip merges smoothly with the inner surface of thelip 52.

Preferably, the plate element 100 extends in the region of a cage 60 andpasses through an recess 102 in its transverse portion 62. Furthermore,the plate element 100 is penetrated by the adjustment bolt 58, whichengages in the first element 70, which, however, as in thecross-sectional view of FIG. 4, is rotated through 180°, in comparisonto the arrangement of FIGS. 5 and 7 to 12, in order to act as a locknut. This is also shown by the extent of the sloping section 90, whichis illustrated by a broken line.

To ensure a drainage of the check rail arrangement 10, a conventionaldrainage box 104 is used which, by means of a funnel-shaped connection108, receives water flowing through openings 106 in the bottom of thefiller piece 40 and along the base plate 36.

The lock bolts 46 for fastening the check rail strip 12 are preferablysecured by Nordlock washers. The adjustment bolts 58 are, in turn,secured in a form-locking manner by washers which are bent at at leastone flat face of the bolt heads.

Furthermore, closure plates 110, 112 should extend from the frontsurface of the secondary rail 28 to the grooved rail 16 in order toobtain a closed system between grooved rail 16 and check rail strip 12and secondary rail 28.
